Linux / Windows: Error code: 0×80070035 cannot access and Error NT_STATUS_HOST_UNREACHABLE

While configuring SAMBA / CIFS and file sharing over the network, the following errors popup eventually after the HTPC is restarted.  A bit baffling at first since SSH works just as it did before the restart.  However the problems persist and look like this: Windows cannot access \\\HTPCBackupXFS Check the spelling of the name.  Otherwise, [...]

Dynamic IP’s: How to find external IP of your Router / Linux machine and ‘ssh’ to it.

Working remotely from various places, I needed to have access to my Linux machine at home. Unfortunately for me, my DSL IP was dynamic and at the time my ISP would change this IP several times a day. That was good for maybe only a few hours and then it would change to something completely [...]

Windows / Linux: Mutually accessing various filesystems on the same PC.

Especially true with dual boot systems, sharing files between two different operating systems on a single PC can become a time consuming task.  One thing many new users do when they install a Linux on a different partition of the same machine, is to try to connect to the other operating systems and files they [...]
